【Abstract】 Objective To evaluate the effect of cognitive behavioral therapy combined with sound therapy on chronic idiopathic tinnitus and its influence factors.Methods A total of 48 patients suffering from chronic idiopathic tinnitus in the people’s hospital of Leshan from June 2018 to June 2020 received cognitive behavioral therapy and sound therapy. Tinnitus handicap inventory (THI)and tinnitus evaluation questionnaire (TEQ) were assessed preand post-treatment to evaluate the effect. At the same time, the age, gender，education level，tinnitus loudness, tinnitus frequency and the degree of hearing loss were analyzed as the independent factor. Results Among 48 patients,5 cases were cured (10.42%)，markedly effective in 13 cases (27.08%)，effective in 13 cases (27.08%)， invalid in 17 cases (35.42%)，the total effective rate was 64.58%.The THI score was 46. 96±9.05 before treatment and 30. 38±14.82 after treatment. The TEQ score was 13. 77±2.36 before and 9. 69±4.20 after treatment. There were significant differences in THI and TEQ scores before and after treatment (P<0.05).The Logistic regression analysis showed that there was no significant difference in age, gender, loudness， frequency and degree of hearing loss (P>0.05), but there was significant difference in level of education (P<0.05).Conclusion Cognitive behavioral therapy combined with sound therapy is an effective treatment on chronic idiopathic tinnitus. The educational level of patients may be an independent factor affecting the treatment effect, while age,gender,loudness,frequency and degree of hearing loss have no significant effect on the treatment effect.
